TS4990IJT
1W AUDIO POWER AMPLIFIER WITH ACTIVE LOW STANDBY MODE
OPERATING FROM VCC = 2.2V to 5.5V
1W OUTPUT POWER @ Vcc=5V, THD=1%, f=1kHz, with 8Ω Load ULTRA LOW CONSUMPTION IN STANDBY
MODE (10nA)
62dB PSRR @ 217Hz @ Grounded mode Zero POP & CLICK ULTRA LOW DISTORTION (0.1%) UNITY GAIN STABLE AVAILABLE IN 9 BUMPS Flip Chip Package
DESCRIPTIONThe TS4990 has been designed for demanding
audio applications such as mobile phones and to
minimize the number of external components.
This Audio Power Amplifier is capable of deliver-
ing 1W of continuous RMS Ouput Power into an
8Ω load @ 5V.
An externally controlled standby mode control re-
duces the supply current to less than 10nA. It also
includes an internal thermal shutdown protection.
The unity-gain stable amplifier can be configured
by external gain setting resistors.
APPLICATIONS Mobile Phones (Cellular / Cordless) Laptop / Notebook Computers PDAs Portable Audio Devices

ABSOLUTE MAXIMUM RATINGS
OPERATING CONDITIONS All voltages values are measured with respect to the ground pin. The magnitude of input signal must never exceed VCC + 0.3V / GND - 0.3V Device is protected in case of over temperature by a thermal shutdown active @ 150°C. This thermal resistance can be reduced with a suitable PCB layout .

ELECTRICAL CHARACTERISTICSVCC = +5V, GND = 0V, Tamb = 25°C (unless otherwise specified)
VCC = +3.3V, GND = 0V, Tamb = 25°C (unless otherwise specified) Standby mode is actived when Vstdby is tied to Gnd Dynamic measurements - 20*log(rms(Vout)/rms(Vripple)). Vripple is the surimposed sinus signal to Vcc. Standby mode is actived when Vstdby is tied to Vcc Dynamic measurements - 20*log(rms(Vout)/rms(Vripple)). Vripple is the surimposed sinus signal to Vcc.

ELECTRICAL CHARACTERISTICSVCC = 2.6V, GND = 0V, Tamb = 25°C (unless otherwise specified)
REMARKS
1. All measurements, except PSRR measurements, are made with a supply bypass capacitor Cs = 1μF.
2. The standby response time is about 1μs. Standby mode is actived when Vstdby is tied to Vcc Dynamic measurements - 20*log(rms(Vout)/rms(Vripple)). Vripple is the surimposed sinus signal to Vcc.
